New antibiotic that kills drug-resistant bacteria found in technician's garden

Historical context: soil as a drug source

• Several comments recall long-standing “bioprospecting” in soil: classic penicillin stories (petri dish contamination; later high-yield cantaloupe strain), and rapamycin’s discovery from Easter Island soil.
• Soil and plants are framed as active “chemical war zones” (bacteria vs bacteria, fungi vs bacteria), providing rich sources of natural antibiotics and other drugs.

“Why not just evolve new antibiotics in dishes/fields?”

• Naive proposals: spray resistant bacteria onto fungi/mushrooms or co-culture pathogens with diverse organisms to see what kills them.
• Objections:
  • Safety: generating large quantities of drug‑resistant pathogens is at least BSL‑3; “spraying fields” is unrealistic.
  • Technical: many microbes won’t grow on plates; the paper itself kept soil on media for a year, highlighting slow, finicky workflows.
  • Some research groups already pursue evolutionary or “sculpted evolution” approaches.

Phage therapy vs antibiotics

• Pro‑phage arguments: highly effective, body clears them (a “feature” not a bug), naturally present in mucus, and can be catalogued/selected per pathogen.
• Skeptical points:
  • Phages are extremely specific; require knowing the exact pathogen and time to find/grow the matching phage, incompatible with urgent empiric treatment.
  • Immune clearance can limit systemic use; best for local or last‑ditch treatments.
  • No strong business model; hard to secure exclusivity, needs state support.
• Some suggest using phages to offload less-urgent infections and preserve antibiotics.

Economics and drug-development barriers

• Repeated theme: poor business case for new antibiotics vs chronic drugs (e.g., obesity treatments). Stewardship means new agents are held in reserve and generate low sales.
• Discussion of high failure rates and costs in drug development; pushback that blaming “capitalism alone” is simplistic, but also that IP and exclusivity drive what gets developed.
• Achaogen is cited as a cautionary tale of a new antibiotic company that collapsed despite scientific success.

Antibiotic use in agriculture

• Strong view: novel antibiotics should be strictly off-limits in livestock; current and past misuse in meat production is seen as a major driver of resistance and morally perverse.
• Others argue for more nuanced regulation: reserve top-tier drugs for humans but allow limited use of lower-tier drugs in animals.
• Notes:
  • Routine prophylactic use is said to be banned in the EU and (to some degree) in the US, though commenters debate loopholes and enforcement.
  • Antifungal overuse in crops (azole fungicides) is highlighted as a parallel, with documented resistant Aspergillus strains.
  • India is mentioned for heavy human antibiotic use; US livestock use is also called out as massive.
• Debate extends into broader politics (protests, US healthcare, regulation), but there is consensus that overuse—in people and animals—is a core problem.

Diet, meat, and environmental concerns

• Some argue that cutting or eliminating livestock agriculture would simultaneously reduce AMR, climate impact, and biodiversity loss; being non‑vegetarian in 2025 is called “unreasonable.”
• Others push back:
  • Meat is part of human omnivory and, historically, agriculture and animal husbandry were sustainable at smaller scales.
  • Access to healthy vegetarian diets is not equal globally.
  • The issue is framed by some as “how we produce meat” (factory farming, density, antibiotics) rather than meat consumption per se.
• Tangents cover climate timelines, personal responsibility vs systemic change, and the difficulty of asking individuals to make large lifestyle sacrifices.

Scientific details and resistance questions

• Commenters note this antibiotic is bacterially produced (bacteria frequently make antibiotics as chemical weapons).
• It reportedly targets the ribosome and is non-toxic to human cells in early assays.
• Skeptics emphasize:
  • Bacteria can still develop resistance via general mechanisms (reduced uptake, efflux pumps) or specific proteases against a peptide antibiotic.
  • Claims that ribosomes are “hard to evolve resistance against” are challenged as incomplete; resistance can and does evolve.

From discovery to usable drug

• Multiple comments stress that finding a molecule is the easy part; taking it through preclinical work and Phase 1–3 trials is “long and arduous.”
• Given current incentives, several fear that even promising new antibiotics may never reach, or stay on, the market.

Global access and stewardship

• One strand argues new “last-resort” antibiotics should be tightly controlled globally, with pre-dosed products shipped rather than open manufacturing to prevent misuse (e.g., for minor coughs).
• Others warn this easily becomes a justice issue if developing countries are denied affordable access; they argue standard antibiotics should at least be broadly available.
